Workshop Notes

Material assignments

Use unique color and layer combination – for example:

level 1, color 0 assign “brick”

level 1, color 1 assign “concrete”

Placement of lights within model space

Create poles on which to mount lights (use separate level, so light pole can

be turned off during rendering)

Light placement – light is automatically placed on construction level, which is

shown in level manager as ‘Default’

Lumens – measures wattage – 1500 lumens approximately 70 Watt

Intensity – ratio

Cone angle – relevant to spotlight

Cell Scale- changes size of construction symbol in model for visibility, but has nothing to

do with lumens or actual size of light source

Settings Rendering Global lighting
